Abstract

Purpose : To determine the association between the severity of upper eyelid margin conjunctivilization (CM) and trachomatous trichiasis (TT) severity as well as to evaluate the association between CM and entropion in TT surgical patients.

Methods : A cross-sectional study was conducted amongst adults with TT who were referred to surgical camps in Bahi District, Tanzania, for TT surgery. Participants underwent ocular examination. The presence and severity of CM was evaluated in photographs of the everted upper eyelid and the presence of entropion was evaluated in a subset of these photographs. TT severity was assessed at the time of the ocular exam based on the number of lashes touching the globe and/or evidence and extent of epilation. Ordinal logistic models were used to examine the association between the severity of CM and TT severity.

Results : A total of 627 eyes of 388 subjects were included. The participant’s mean age was 64.6 years, 81% were females, and 62% had bilateral TT. 75.2% of the eyes had severe conjunctivilization of the lid margin and 42% of the eyes had severe trichiasis. An increase in the severity of CM was associated with an increase in TT severity. Using as a reference eyes with none to mild CM, the odds of increased TT severity per one level increase in CM severity was 2.12 (95% CI: 1.56, 2.88).

Conclusions : In cases of trachomatous trichiasis presenting for surgery, TT severity was significantly associated with the severity of CM. Almost all cases of TT had moderate or severe CM. CM could be a useful adjunct in helping determine who needs trichiasis surgery.
